RBC Pathway And Abnormalities Flashcards
Effect of gender in RBC count
Estrogen inhibits erythropoiesis. Decrease RBC count
Androgen stimulates erythropoiesis. Increase RBC count
Erythrocytes normal values in conventional unit
Male: 5.5-6.5 million/cu.mm
Female: 4.5-5.5 million/cu.mm
Decrease oxygen means?
Increase erythropoiesis. Increase RBC count
Conditions with increase RBC count
Polycythemia Vera Chronic heart disease Dehydration Lung disease Acute poisoning Residing in a place with high altitude
Conditions with decrease RBC count
